![]() This can be attributed to local physical situations and wind direction properties. Most of them were slim (166 barchans, 42.5%) and their distribution differed between the eastern and western parts of the Lut Desert. The shape of barchans was classified into slim, normal, pudgy, or fat and extraordinarily slim. Results of measuring the morphometric parameters of the barchans indicated that mean length, width, height, and maximum length of barchans were equal to 114.5, 179.5, 10.47, and 590.2 m, respectively which are relatively high in comparison with data for other barchans studied in some previous researches in the world. Their direction of movement ranged from northwest to southeast in the western part and from southwest to northeast in the eastern part, which were correlated with the dominant wind directions in these regions. NASA figures show that between 20 (except for 2008 when Turpan Depression in north of China won the title. With temperatures as high as 71 ☌, Lut is aptly called ‘the Pole of Heat on earth.’. The NNW direction (620 VU) in the west as well as the SSW direction (100 VU) had a high effect on the movement of barchans. 07 (MNA) A NASA satellite record of temperature in Lut desert in Iran shows the desert as the hottest place on earth. ![]() The annual sand drift potential was equal to 1053.9 VU in the western part and 803.6VU in the eastern part of the Lut Desert and it was classified as high-energy wind environment. The lake was created after the floods of the current year (2019) and the overflow of the Shur River which emanates from the southern Khorasan highlands and goes to the end of the desert in the south of Lut in Kerman province. The mean migration rate was about 5.17 m/yr in the study area and ranged between 1.1 and 15.35 m/yr. The results showed big difference in the morphology, morphometry, and direction and migration rate of barchans between the western and eastern parts of the Lut Desert. Therefore, herein, a total of 391 individual barchan dunes were selected and their morphometric parameters were compared with respect to the length/width (a/c) ratios (extraordinarily slim to fat barchans), migration rate, direction of movement and influence of wind regime on this landform. This scorching and lesser-known area, that extends from north to south, is bounded on the west by the Nayband fault and on the east by the Nehbandan fault. This region is one of the driest places in the world and there is a little information about the geomorphology of this region, especially on the barchans. Lut Desert is a vast area that includes parts of the three vast provinces of Sistan and Baluchestan, South Khorasan and Kerman. The present research was conducted to determine the morphometry, morphology, and temporal and spatial behavior of individual barchans in the Lut Desert in Iran.
